Rake gutter, gutter cutting edge, and gutter and shingle

Abstract

A combination drip edge, rake flashing, gutter with nail flange that is useful for water harvesting and securing of shingles in adverse weather conditions.

Description

RELATED APPLICATIONS[0001]This application claims the benefit of U.S. Provisional Application No. 62 / 514,406, filed Jun. 2, 2017. This application is herein incorporated by reference in its entirety for all purposes.FIELD OF THE INVENTION[0002]The invention relates to a roofing drip edge, and more particularly, to a rake drip edge, which acts like a rake edge gutter and provides for a shingle cutting guide and a shingle locking mechanism.BACKGROUND OF THE INVENTION[0003]The vast majority of sloped roofing systems installed in North America are asphalt shingle systems. Such installations generally require the installation of drip edges, which help to seal the building against water intrusion, adjacent edges of the building envelope. After installing one of these drip edges at the rake and eave, a starter shingle is typically installed on top of a drip edge. Then field shingles are installed onto the starter shingles using fasteners, with the possible combination of plastic roof cemen...

Benefits of technology

[0017]A cutting guide in accordance with embodiments of the present disclosure also allows a hooked blade or other cutting device to be used in an abutment area or groove of the rake edge gutter, even when hidden under field shingles extending onto and over the cutting guide.

[0020]This downward angled securement extension puts less pressure on the rake edge from weather forces traveling across the roof plane by catching less wind, while the downward angled hem, in conjunction with the elevated exterior plane and cutting edge of embodiments, diverts water back towards the rake gutter area. Furthermore, weather forces directed towards the gable end of a roof tend to push the downward angled hem into the field shingle, resulting in additional field shingle securement during high wind events. While on site, should a ladder need to be placed up against the gable of embodiments of the gutter disclosed herein, the downward angled hem imbeds itself further into the field shingle while providing for less movement of the drip edge and the ladder, increasing safety.

[0024]Yet another embodiment of the present disclosure provides such a drip edge wherein the shingle-securing section comprises a top portion of the gutter configured to be folded over onto the shingle, following the installation thereof, thereby securing the shingle against wind uplift while simultaneously hiding the cut edge thereof.

[0025]A yet further embodiment of the present disclosure provides such a drip edge wherein an interface between the gutter and the shingle securing section thereof is pre-weakened, thereby allowing the section to be more easily bent over a shingle.

[0039]One embodiment of the present disclosure provides a rake edge gutter, the rake edge gutter comprising: an upper section, a lower section opposite the upper section, an outer section and an inner section opposite the outer section, wherein the inner section is configured to be positioned behind, and terminate below, a rake edge, abutting against a building envelope, following installation of the rake edge gutter on a rake edge, wherein the outer section is substantially taller than the inner section and is configured to extend above a rake edge following installation of the rake edge gutter on a rake edge, wherein the lower section connects the inner section to the outer section and is configured to extend past a rake edge following installation of the rake edge gutter on a rake edge, wherein the upper section further comprises a proximal portion fixed to the outer section and a distal end positioned closest to the inner section of the rake edge gutter, and wherein the distal portion of the upper section further comprises a protrusion angled towards the inner section, the protrusion configured to hide the cut edge of a shingle, act as a barrier against cross-winds that could cause shingle uplift, and capture moisture blown across the field of a roof and direct it into the gutter formed by the C-shaped channel formed by the inner, outer, and lower sections of the rake edge gutter.

Problems solved by technology

The rapid increase in the use of “architectural” shingles has had an unforeseen consequence.

For this reason, the roof mechanic, if presented with the option, will cut the field shingle where the underlay area runs through the entire field shingle with the unforeseen consequence of additional water moving towards the rake edge.
